Will this always correctly determine if the platform is big-endian? How does it actually work?
I don't know, having not used things like peekByteOff, but my suspicion would be that it's rather like, typedef char byte; char cChar = 1; int cInt = 1; int be = cChar != *(((byte*) &cInt) + 0); printf("be = %i\n", be); return 0; in C, so it's looking to see if the first byte of the int representation of 1 isn't 1. -- Mark
